Document
In the context of IBM mainframes and z/OS, a "document" typically refers to a **dataset**, which is a named collection of related data or programs stored on a direct access storage device (DASD) or magnetic tape. It serves as the fundamental unit for storing information that can be processed by applications, utilities, or the operating system itself. In the mainframe context, a **Document** broadly refers to a structured collection of data or information, typically stored as a **data set** (file) or a logical unit within a database (data object) on z/OS. Unlike PC-centric documents, mainframe "documents" often represent application data, configuration files, reports, or source code, and are managed by the operating system or database management systems.
